"The pinnacle philosophy at play in planning this event is the balance of yin and yang. We’ll rely on it for decor, food choices, background music, everything! The ceremony during the day will balance with the reception at night.” (bride in a white wedding dress with groom in black tux and bride in a black evening gown with groom in white tux.)
